新疆地区一株马流感病毒的分离及鉴定

Isolation and identification of equine influenza virus in Xinjiang

2007年10月,我国新疆维吾尔自治区阿勒泰地区富蕴县发现马匹出现呼吸道疾病,发病马表现出典型的流行性感冒症状。经过临床诊断、病原分离、电镜观察以及病毒基因序列分析,确定病原为马流行性感冒病毒,属于H3N8亚型,该株病毒与近年来马流行性感冒病毒北美洲流行株的同源性较高,命名为A/equine/XinjiangFuyun/3/2007(H3N8)。

An equine influenza virus was isolated from horses showing typical influenza symptoms in Fuyun County of Xinjiang province in October 2007. Electron microscope observation and sequence analysis confirmed that the virus belonged to H3N8 subtype and was highly homologous with equine influenza virus American isolates.
